Thermal placement of elements of integrated circuits on crystal surface
Pleiades Publishing Ltd - Tập 52 - Trang 276-280 - 2017
A. G. Harutyunyan
The criterion and the corresponding approach for the thermal placement of integrated circuits (IC) elements on the crystal surface are proposed. The criterion of placement is identical to the traditional criteria of minimizing the total length of connections between elements, which at the placement stage enables to apply an additive multiparametric criterion of joint consideration of electrical an... hiện toàn bộ
Numerical simulation of propagation of a femtosecond optical soliton in a single-mode fiber with allowance for the imaginary part of Raman response
Pleiades Publishing Ltd - Tập 45 Số 6 - Trang 251-257 - 2010

On the production of Λ- and Ω-hyperons in nucleus-nucleus collisions
Pleiades Publishing Ltd - Tập 50 - Trang 297-301 - 2015
V. M. Zhamkochtan
The processes of production of Λ0- and Ω--hyperons in collisions of two nucleus are considered in the nucleon fragmentation region of an incident nucleus. The inclusive spectra of these processes are calculated for different target nuclei. The presented results may be used for analyzing the fragmentation mechanisms as well as the accuracy of the model approximations used.
Methods of Production the Isotope 67Cu
Pleiades Publishing Ltd - Tập 55 - Trang 183-190 - 2020
G. H. Hovhannisyan, A. V. Stepanyan, E. R. Saryan, L. A. Amirakyan
The nuclear reactions on zinc isotopes leading to the formation of the medical theranostic isotope 67Cu have been investigated. Model calculations were made using the TALYS1.9 code. The results are compared with the published experimental data. The comparison of calculated and experimental data showed a satisfactory agreement in the case of the proton-nuclear reactions. In the case of the calculat... hiện toàn bộ

Anti-Reflection Properties of Black Silicon Coated with Thin Films of Metal Oxides by Atomic Layer Deposition
Pleiades Publishing Ltd - Tập 56 - Trang 240-246 - 2021
G. Y. Ayvazyan, M. V. Katkov, M. S. Lebedev, V. R. Shayapov, M. Yu. Afonin, D. E. Petukhova, I. V. Yushina, E. A. Maksimovskii, A. V. Aghabekyan
The results of experimental studies of the anti-reflection properties of black silicon (b-Si) layers coated with thin films of TiO2, HfO2, and Sc2O3 metal oxides by atomic layer deposition (ALD) are presented. An improvement in the antireflection properties of b-Si in a wide spectral range is shown. It is expedient to use the investigated ALD films in solar cells as an effective passivating coatin... hiện toàn bộ
Dependence of the Conductivity Mechanism and Dielectric Properties of Zinc Oxide Films on the Degree of Lithium Doping
Pleiades Publishing Ltd - Tập 58 - Trang 274-281 - 2023
N. R. Aghamalyan, H. L. Ayvazyan, T. A. Vartanyan, Y. A. Kafadaryan, H. G. Mnatsakanyan, R. K. Hovsepyan, A. R. Poghosyan
The effect of lithium impurity on the dielectric characteristics and the mechanism of conductivity of zinc oxide thin films obtained by the electron beam deposition method was studied. At low frequencies, a strong dispersion of permittivity constants associated with interfacial polarization at grain boundaries was found. It was shown that the frequency dependencies of the conductivity are well des... hiện toàn bộ
Noise in porous silicon structures in air and in conditions of gas adsorption
Pleiades Publishing Ltd - Tập 43 - Trang 131-135 - 2008

Low-frequency noise, in the range 1–500 Hz, is measured at room temperature in samples of Au/PS/SCS/Al structure with a layer of porous silicon. Numerical values of the Hooge parameter αH are estimated and the dependence of αH on the composition of the gaseous environment, where the sample is placed, is determined. Possible reasons of observed high values of αH for the samples in air and of the in... hiện toàn bộ
